Bacchiacca developed an individual manner of painting characterized by attention to ornament, particularly jewelry, and vivid color combinations. A celebrated drawing by Michelangelo of 'Teste Divine (Zenobia)' (housed in Gallerie degli Uffizi, Gabinetto Disegni e Stampe, Florence) was the model for the female figure, but Bacchiacca changed her allegorical identity to the virtue of Liberality. The elaborately dressed personification loosens the strings of a coin purse, suggesting that she is about to distribute her riches.

This painting was previously attributed to French artist Jean Fouquet (born about 1415 - 1420, died before 1481). The examiner's attribution was based on stylistic analysis of the painting; namely, the appearance of a French coin in the half-opened purse and the jewelry on the lady, which is "almost identical to that worn by Diana of Tours in Francois Clouet's portrait."
